Gum and tooth sensitivity causes and management
Sensitivity can come from exposed dentine, enamel wear, gum recession, decay, a crack, or pulp inflammation, so treatment depends on the finding.
What causes gum or tooth sensitivity and how is it managed?
Sensitivity can come from exposed dentine, enamel wear, gum recession, decay, a crack, or pulp inflammation, so treatment depends on the finding.
How can exposed dentine make teeth feel sensitive?
Dentine contains microscopic tubules that can transmit temperature or touch toward the pulp when enamel is worn or the root surface is exposed. A short sharp response differs from pain that lingers, starts without a trigger, or is linked to chewing.
What can you do to reduce everyday tooth sensitivity?
Use a soft brush and gentle pressure, clean between the teeth, and consider a desensitising toothpaste used consistently as directed. Avoid repeatedly testing the painful tooth and arrange an examination to identify decay, a defective restoration, wear, recession, or a pulp problem.
When does tooth sensitivity need a dental examination?
See a dentist when sensitivity persists, increases, affects one tooth, or follows a filling, whitening treatment, crack, or dental injury. Swelling, fever, or severe spontaneous pain needs prompt care.
What should you ask about the source of sensitivity?
Ask where the sensitivity originates, whether the pulp is healthy, and whether fluoride treatment, bonding, a filling, bite adjustment, or root canal treatment is indicated.
Frequently asked questions
Can home care replace a dental examination?
Home care may ease a symptom, but it cannot identify or correct decay, infection, gum disease, a crack, or a failing restoration.
What changes make this more urgent?
Rapid worsening, swelling, fever, heavy bleeding, severe pain, or difficulty swallowing or breathing calls for prompt dental or emergency assessment.
